[0047] The proposed power supply system 1a will be described below with reference to FIGS. 2 to 8. FIG.

[0048] 2 is a sequence diagram for explaining the evaluation of the proposed power supply system 1a. This evaluation is performed using an EMS server 52, a natural phenomenon server 53, a ground information server 54, and a terminal 58. The EMS server 52, the natural phenomenon server 53, the ground information server 54, and the terminal 58 are connected to each other via a network 60. An evaluation system 59 is configured that includes the EMS server 52, the natural phenomenon server 53, the ground information server 54, and the terminal 58.

[0049] The natural phenomenon server 53 and the ground information server 54 may each be a cloud server or an on-premise server. The terminal 58 is, for example, a smartphone, a personal computer, a tablet, a mobile phone, a personal digital assistant (PDA), or the like.

[0050] The terminal 58 is used by a proposer 57. The proposer 57 proposes to the owner of the facility that the power supply system 1a be installed in the facility. The facility is built on a site 81, which is included in a district 85. The proposer 57 is, for example, a business operator. The facility is, for example, a factory. FIG. 3 is a schematic top view showing the district 85 and the site 81. FIG. 4 is a schematic top view showing the location of the power supply system 1a whose installation is proposed. In FIG. 3, boundaries between multiple districts are indicated by thick lines. The district 85 is one of the multiple districts and is schematically indicated by diagonal hatching. In FIGS. 3 and 4, the site 81 is schematically indicated by dotted hatching. In FIG. 4, the location of the power supply system 1a is schematically indicated by a solid line. In FIGS. 3 and 4, the facilities are not shown.

[0051] 2, the terminal 58 transmits the extent of the site 81 to the EMS server 52. In step S2, the EMS server 52 transmits the extent of the site 81 to the ground information server 54. In step S3, the EMS server 52 transmits the extent of the site 81 to the natural phenomenon server 53.

[0052] The range of the site 81 is specifically the range of longitude and latitude that the site 81 extends in. The range of the site 81 transmitted from the terminal 58 in step S1 is, for example, the range that the proposer 57 inputs into the terminal 58.

[0053] In step S4, the ground information server 54 transmits the ground information in the area 85 to the EMS server 52. In step S5, the natural phenomenon server 53 transmits the natural phenomenon information in the area 85 to the EMS server 52.

[0054] The ground information includes elevation information and ground hardness information. The elevation information has an elevation value. The ground hardness information has a ground hardness value. Fig. 5 is a chart showing an example of ground information. Fig. 5 illustrates an example of ground information for a site 81.

[0055] The natural phenomenon information includes sunshine information, rainfall information, flooding information, and earthquake information. The sunshine information has the amount of sunshine for each unit period in the past. The rainfall information has the amount of rainfall for each unit period in the past. The flooding information has the presence or absence of flooding and the depth of the flooding for each unit period in the past. The earthquake information has the presence or absence of earthquakes and the magnitude of the earthquakes for each unit period in the past. The unit period is, for example, one month.

[0056] The district 85 is divided into a plurality of unit plots 82. In the examples of Figures 3 and 4, the size of one unit plot 82 is smaller than the size of the site 81. In the district 85, the ground information is information with position resolution in which a value is assigned to each unit plot 82. This makes it possible to distinguish between the ground information at the longitude and latitude of each facility in the proposed power supply system 1a. The same applies to the elevation information and ground hardness information. In Figure 4, the boundaries of the unit plots 82 are schematically shown by dotted lines.

[0057] 2 , the terminal 58 transmits PV information to the EMS server 52. In step S7, the terminal 58 transmits FC information to the EMS server 52. In step S8, the terminal 58 transmits SB information to the EMS server 52. The PV information is information related to the photovoltaic power generation facility 10. The FC information is information related to the fuel cell facility 20. The SB information is information related to the storage battery facility 30.

[0058] The photovoltaic power generation facility 10 proposed for introduction includes one or more PV component facilities. The fuel cell facility 20 proposed for introduction includes one or more FC component facilities. The storage battery facility 30 proposed for introduction includes one or more SB component facilities. The PV information includes the facility size of one or more PV component facilities and the longitude and latitude of the one or more PV component facilities. The FC information includes the facility size of one or more FC component facilities and the longitude and latitude of the one or more FC component facilities. The SB information includes the facility size of one or more SB component facilities and the longitude and latitude of the one or more SB component facilities. The PV information, FC information, and SB information transmitted from the terminal 58 in steps S6 to S8 are, for example, input into the terminal 58 by the proposer 57.

[0059] In the embodiment, the scale of the PV-component facility is expressed by a value corresponding to the number of photovoltaic power generation modules in the PV-component facility, the scale of the FC-component facility is expressed by a value corresponding to the number of fuel cell stacks in the FC-component facility, and the scale of the SB-component facility is expressed by a value corresponding to the number of storage battery modules in the SB-component facility.

[0060] In step S9, the EMS server 52 calculates: (pv1) the possibility that one or each PV component equipment in the solar power generation equipment 10 will be flooded; (pv2) the amount of damage expected to the solar power generation equipment 10 if one or each PV component equipment in the solar power generation equipment 10 is flooded; (fc1) the possibility that one or each FC component equipment in the fuel cell equipment 20 will be flooded; (fc2) the amount of damage expected to the fuel cell equipment 20 if one or each FC component equipment in the fuel cell equipment 20 is flooded; (sb1) the possibility that one or each SB component equipment in the storage battery equipment 30 will be flooded; and (sb2) the amount of damage expected to the storage battery equipment 30 if one or each SB component equipment in the storage battery equipment 30 is flooded.

[0061] The possibility of (pv1) above and the amount of damage (pv2) above are calculated based on the following: - The equipment size of 1 or each PV component equipment; - Altitude information in longitude and latitude of 1 or each PV component equipment; - Rainfall information in area 85; and - Flooding information in area 85.

[0062] The possibility of (fc1) above and the amount of damage of (fc2) above are calculated based on the following: - The equipment size of 1 or each FC component equipment, - Altitude information in the longitude and latitude of 1 or each FC component equipment, - Rainfall information in area 85, and - Flooding information in area 85.

[0063] The possibility of (sb1) above and the amount of damage of (sb2) above are calculated based on the following: - The equipment size of 1 or each SB component equipment; - Altitude information in the longitude and latitude of 1 or each SB component equipment; - Rainfall information in area 85; and - Flooding information in area 85.

[0064] In step S10, the EMS server 52 calculates: (pv3) the amount of damage expected to the solar power generation equipment 10 if an earthquake of each seismic intensity occurs in the area 85; (fc3) the amount of damage expected to the fuel cell equipment 20 if an earthquake of each seismic intensity occurs in the area 85; and (sb3) the amount of damage expected to the storage battery equipment 30 if an earthquake of each seismic intensity occurs in the area 85.

[0065] The amount of damage (PV3) above is calculated based on the following: - The equipment size of 1 or each PV component equipment; - Ground hardness information at the longitude and latitude of 1 or each PV component equipment; and - Earthquake information in area 85.

[0066] The amount of damage in (fc3) above is calculated based on: - the equipment scale of 1 or each FC component equipment; - information on ground hardness at the longitude and latitude of 1 or each FC component equipment; and - earthquake information in district 85.

[0067] The amount of damage in (sb3) above is calculated based on the following: - The equipment size of 1 or each SB component equipment; - Ground hardness information at the longitude and latitude of 1 or each SB component equipment; and - Earthquake information in area 85.

[0068] In step S11, the EMS server 52 calculates a disaster damage index. The disaster damage index indicates the evaluation result of damage to the power supply system 1a, the introduction of which is proposed, caused by a natural disaster. The disaster damage index includes a flood damage index, an earthquake damage index, and a comprehensive damage index. The flood damage index indicates the evaluation result of damage to the power supply system 1a, the introduction of which is proposed, caused by flooding. The earthquake damage index indicates the evaluation result of damage to the power supply system 1a, the introduction of which is proposed, caused by an earthquake. The comprehensive damage index indicates the evaluation result of a comprehensive evaluation of damage to the power supply system 1a, the introduction of which is proposed, caused by a natural disaster. Specifically, the flood damage index is a normalized flood damage expectation value. The earthquake damage index is a normalized earthquake damage expectation value. These normalizations are performed according to a predetermined standard. The normalization can be performed, for example, by dividing the expectation value by a predetermined value. The comprehensive damage index is the sum of the flood damage index and the earthquake damage index.

[0069] Here, the number of PV component equipment in the photovoltaic power generation equipment 10 is denoted as p, where p is a natural number equal to or greater than 1. The number of FC component equipment in the fuel cell equipment 20 is denoted as q, where q is a natural number equal to or greater than 1. The number of SB component equipment in the storage battery equipment 30 is denoted as r, where r is a natural number equal to or greater than 1.

[0070] The expected flood damage value is calculated, for example, using the following formula 1.

[0071] In Equation 1, the purchase price of the a-th PV component equipment can be used as the expected damage amount to the a-th PV component equipment if the a-th PV component equipment is flooded, the purchase price of the b-th FC component equipment can be used as the expected damage amount to the b-th FC component equipment if the b-th FC component equipment is flooded, and the purchase price of the c-th SB component equipment can be used as the expected damage amount to the c-th SB component equipment if the c-th SB component equipment is flooded.

[0072] The expected earthquake damage value is calculated, for example, by the following Equation 2.

[0073] In Equation 2, n is, for example, 7. In Equation 2, the expected damage amount to the a-th PV component equipment if an earthquake of seismic intensity k occurs in district 85 can be the purchase price of the component of the a-th PV component equipment that is expected to fail if an earthquake of seismic intensity k occurs in district 85, the expected damage amount to the b-th FC component equipment if an earthquake of seismic intensity k occurs in district 85 can be the purchase price of the component of the b-th FC component equipment that is expected to fail if an earthquake of seismic intensity k occurs in district 85, and the expected damage amount to the c-th SB component equipment if an earthquake of seismic intensity k occurs in district 85 can be the purchase price of the component of the c-th SB component equipment that is expected to fail if an earthquake of seismic intensity k occurs in district 85.

[0074] In step S12, the EMS server 52 calculates the power generation capacity of the proposed photovoltaic power generation facility 10. In step S13, the EMS server 52 calculates the power generation capacity of the proposed fuel cell facility 20. In step S14, the EMS server 52 calculates the power storage capacity of the proposed storage battery facility 30.

[0075] The power generation capacity of the solar power generation facility 10 is calculated based on sunshine information in the area 85, the size of the solar power generation facility 10, etc. The power generation capacity of the fuel cell facility 20 is calculated based on the size of the fuel cell facility 20, etc. The power storage capacity of the storage battery facility 30 is calculated based on the size of the storage battery facility 30, etc. Specifically, the power generation capacity of the solar power generation facility 10 corresponds to the predicted value of the amount of power generated by the solar power generation facility 10 over a predetermined period. The power generation capacity of the fuel cell facility 20 corresponds to the predicted value of the amount of power generated by the fuel cell facility 20 over a predetermined period. The power storage capacity of the storage battery facility 30 corresponds to the maximum amount of power stored in the storage battery facility 30. The predetermined period is, for example, one year.

[0076] In step S15, the EMS server 52 calculates a power supply index. The power supply index indicates the evaluation result of the power supply capacity of the power supply system 1a, the introduction of which is proposed. The power supply index includes a PV supply index, an FC supply index, and an SB supply index. The PV supply index indicates the evaluation result of the power generation capacity of the photovoltaic power generation facility 10, the introduction of which is proposed. The FC supply index indicates the evaluation result of the power generation capacity of the fuel cell facility 20, the introduction of which is proposed. The SB supply index indicates the evaluation result of the power storage capacity of the storage battery facility 30, the introduction of which is proposed. Specifically, the PV supply index is a normalized predicted value of the amount of power generated by the photovoltaic power generation facility 10 over a predetermined period. The FC supply index is a normalized predicted value of the amount of power generated by the fuel cell facility 20 over a predetermined period. The SB supply index is a normalized maximum amount of power stored in the storage battery facility 30. These normalizations are performed according to a predetermined standard. The normalization can be performed, for example, by dividing an expected value by a predetermined value.

[0077] In step S16, the EMS server 52 transmits the disaster damage index to the terminal 58. In step S17, the EMS server 52 transmits the power supply index to the terminal 58. In step S18, the terminal 58 displays the disaster damage index and the power supply index. By viewing this display, the disaster damage index and the power supply index can be confirmed. The proposer 57 can propose to the facility owner, while showing the facility owner the backing provided by the power supply index, that the facility owner introduce a power supply system 1a that balances the risk of damage caused by natural disasters with the power supply capacity. Furthermore, with the backing provided by the power supply index, the facility owner can understand the TCO of the proposed power supply system 1a and make an appropriate investment decision.

[0078] Steps S6 to S18 in FIG. 2 can be executed according to the number of patterns of the power supply system 1a proposed for introduction. If there is one pattern of the power supply system 1a proposed for introduction, steps S6 to S18 are executed for that one pattern. If there are multiple patterns of the power supply system 1a proposed for introduction, steps S6 to S18 are executed for those multiple patterns. Specifically, in this case, PV information, FC information, and SB information for the multiple patterns are transmitted in steps S6 to S8. Calculations are performed for the multiple patterns in steps S9 to S15. In steps S16 and S17, disaster damage indexes and power supply indexes for the multiple patterns are transmitted. In step S18, disaster damage indexes and power supply indexes for the multiple patterns are displayed. In this embodiment, there are three patterns: pattern A, pattern B, and pattern C.

[0079] The top view in FIG. 4 relates to Pattern A. FIG. 6 is a chart showing the location, installation size, and purchase price of each piece of equipment in Pattern A. FIG. 7 is a chart showing indicators for Pattern A, Pattern B, and Pattern C. In the examples of FIGS. 4, 6, and 7, each combination of a longitude selected from longitudes A1 and A2 and a latitude selected from latitudes B1, B2, B3, or B4 represents a coordinate range. In the embodiment, this combination is referred to as an "area." Each area corresponds to one unit section 82. In FIG. 4, "PV x Numerical Value" indicates the size of the PV component equipment in the corresponding area, indicated by a numerical value after "x." "FC x Numerical Value" indicates the size of the FC component equipment in the corresponding area, indicated by a numerical value after "x." "SB x Numerical Value" indicates the size of the SB component equipment in the corresponding area, indicated by a numerical value after "x."

[0080] The following describes techniques that can be applied to the above-described embodiments.

[0081] In the above-described embodiment, the range of the site 81 is transmitted in steps S1 to S3. Typically, the boundaries of the site 81 are set in some form. However, instead of the range of the site 81, any range including the facility may be transmitted. Furthermore, if the target district 85 in the processing of FIG. 2 is determined in advance, steps S1 to S3 may be omitted. For example, if the geographic range of the business activities of the proposer 57 is determined in advance, steps S1 to S3 may be omitted.

[0082] In the above-described embodiment, in the district 85, the ground information is information having a position resolution in which a value is assigned to each unit block 82. Typically, the unit block 82 is a two-dimensional block extending along the longitude and latitude directions. Also, typically, the size of each unit block 82 is uniform. However, the size of each unit block 82 may vary. The size of the unit block 82 of the elevation information and the size of the unit block 82 of the ground hardness information may be the same or different from each other.

[0083] In the above-described embodiment, the natural phenomenon information, sunshine information, rainfall information, flooding information, and earthquake information are information in which a value is assigned for each district. In a modified example, the natural phenomenon information, sunshine information, rainfall information, flooding information, and earthquake information are information having a position resolution in which a value is assigned for each unit block 82. The sizes of the unit blocks 82 for sunshine information, the unit blocks 82 for rainfall information, the unit blocks 82 for flooding information, and the unit blocks 82 for earthquake information may be the same or different from each other.

[0084] In the above-described embodiment, the natural phenomenon information, sunshine information, rainfall information, flooding information, and earthquake information are information about phenomena that occurred in the past. However, the natural phenomenon information, sunshine information, rainfall information, flooding information, and earthquake information may also be information that is predicted for the future. The natural phenomenon information, sunshine information, rainfall information, flooding information, and earthquake information may also be based on a hazard map.

[0085] In the above-described embodiment, normalization is performed in steps S11 and S15. However, normalization is not essential. For example, the expected flood damage value itself may be used as the flood damage index. The expected earthquake damage value itself may be used as the earthquake damage index. The predicted value of the power generation amount of the photovoltaic power generation facility 10 for a specified period may be used as the PV supply index. The predicted value of the power generation amount of the fuel cell facility 20 for a specified period may be used as the FC supply index. The maximum storage capacity of the storage battery facility 30 itself may be used as the SB supply index.

[0086] In the above-described embodiment, the power supply index includes a PV supply index, an FC supply index, and an SB supply index. The power supply index may also include an overall supply index. The overall supply index is an evaluation result obtained by comprehensively evaluating the power generation capacity of the photovoltaic power generation facility 10 proposed for introduction, the power generation capacity of the fuel cell facility 20 proposed for introduction, and the power storage capacity of the storage battery facility 30 proposed for introduction. The overall supply index is, for example, the sum of the PV supply index, the FC supply index, and the SB supply index. When the overall supply index is applied to the example of FIG. 7 , the overall supply index of pattern A is 5 + 3 + 3 = 11, the overall supply index of pattern B is 3 + 5 + 3 = 11, and the overall supply index of pattern C is 4 + 4 + 3 = 11.

[0087] A system overall index may be calculated by comprehensively evaluating the overall loss index and the overall supply index. In one example, the system overall index is obtained by dividing the overall supply index by the overall loss index. In this example, the higher the system overall index, the more advantageous it may be for the owner.

[0088] In the above-described embodiment, each area corresponds to one unit section 82. However, each area may be larger than one unit section 82. Furthermore, the size of each area may or may not be an integral multiple of the size of one unit section 82.

[0089] In the above-described embodiment, the unit of the amount of stored power is watt-hours (Wh), but other units such as ampere-hours (Ah) may also be used as the unit of the amount of stored power.

[0090] The order of the steps in the sequence diagram of Fig. 2 can be changed as appropriate. For example, steps S1 to S5 may be executed first, followed by steps S6 to S8, or steps S6 to S8 may be executed first, followed by steps S1 to S5.

[0091] In the above-described embodiment, the process of the sequence diagram of Fig. 2 is executed for a power supply system 1a that has not yet been constructed. However, the process of the sequence diagram of Fig. 2 may also be executed for a power supply system 1a that has already been constructed. Specifically, the evaluation by the process of the sequence diagram of Fig. 2 is an evaluation of the power supply system 1a by simulation, and may be executed for any power supply system 1a.

[0092] In the embodiment described above, a natural phenomenon server 53 and a ground information server 54 are used as shown in Fig. 2. In the modified example shown in Fig. 8, a weather information server 55 and a land information server 56 are used.

[0093] 8 , in step S102, the EMS server 52 transmits the extent of the site 81 to the land information server 56. In step S103, the EMS server 52 transmits the extent of the site 81 to the weather information server 55. In step S104, the land information server 56 transmits land information for the district 85 to the EMS server 52. In step S5, the weather information server 55 transmits weather information for the district 85 to the EMS server 52.

[0094] The land information for the district 85 includes elevation information, ground hardness information, and earthquake information for the district 85. The weather information for the district 85 includes sunshine information, rainfall information, and flood information for the district 85.

[0095] 8 , the land information server 56 provides the EMS server 52 with ground information for the district 85. As described above, the ground information includes elevation information and ground hardness information. Furthermore, the combination of the weather information server 55 and the land information server 56 provides the EMS server 52 with natural phenomenon information for the district 85. As described above, the natural phenomenon information includes sunshine information, rainfall information, flooding information, and earthquake information.

[0096] In another variation (not shown), steps S2 to S5 are replaced with steps involving a single server. Specifically, the EMS server 52 transmits the extent of the site 81 to the single server. The single server transmits elevation information, ground hardness information, sunshine information, rainfall information, flood information, and earthquake information for the district 85 to the EMS server 52.
